These are not really the same size class, and that is the honest framing here. The JBL Partybox Encore Essential 2 ranks #6 of 76 boombox speakers by sound quality at $259; the JBL Xtreme 4 ranks #40 of 82 large speakers by sound quality at $309.95.
What the JBL Partybox Encore Essential 2 does well: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. The tradeoff: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume.
Why pick the JBL Xtreme 4: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Watch for: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume.
Buy the JBL Partybox Encore Essential 2 at $259 for a boombox speaker, or the JBL Xtreme 4 at $309.95 for a large speaker instead.
If battery life is a priority, the JBL Xtreme 4 is rated for 24 hours versus 15 hours for the JBL Partybox Encore Essential 2.
Water resistance is not close: the JBL Xtreme 4 is rated at IP67 (brief submersion), well ahead of the JBL Partybox Encore Essential 2 at IPX4 (splashing).

The Two Speakers In Full
JBL Partybox Encore Essential 2: $259.00 Amazon B&H Photo Video eBay
Older model: the JBL Partybox Encore Essential (rated 4.2/5).
Pros: A compact 6.2kg party speaker with 100W output, 110dB maximum level, a 15-hour claimed battery, app-based 7-band EQ, dynamic lighting, USB playback, guitar and mic inputs, and Auracast linking. Independent testing finds a balanced midrange, genuinely punchy low bass and enough output for a backyard gathering; its dome tweeters also improve the earlier Encore’s high-frequency behavior.
Cons: It is front-facing, so the sound changes noticeably to the sides and behind it, and bass compression reduces kick-drum impact at maximum volume. Bluetooth latency can cause lip-sync issues, its IPX4 rating only covers splashes, and it omits the wireless microphones bundled with the non-Essential Encore 2.

JBL Xtreme 4: $309.95 Amazon B&H Photo Video eBay
Newer model: the JBL Xtreme 5, rated 4.6/5.
Pros: A rugged 2.1kg portable with IP67 protection, a replaceable battery, USB-C power-bank output, Auracast, stereo pairing and a useful 5-band app EQ. Independent reviews find the midrange detailed and the sound clear, punchy and refined for outdoor use; it also reaches a strong 106dB maximum level and has excellent real-world battery life.
Cons: It cannot produce the deep rumble of a larger speaker, and bass compression increases near maximum volume. The front-facing layout has only modest off-axis consistency, Bluetooth latency is high for video, and the default balance benefits from EQ adjustment. There is no aux input, so wired sources are not supported. Out of the box it leans bass-boosted, with a dip between the upper bass and midrange that EQ cannot fix, and it pushes the upper mids and treble at high volume. It is also expensive.
